A highly active defect engineered Cl-doped carbon catalyst for the N2 reduction reaction

A one-step synthesis of precursors by mixing Zn(CH₃COO)₂, H₃BTC, and NaCl solution together, followed by carbonization in a nitrogen flow at 900 °C for 3 h. The defect-rich carbons containing –Cl and –COCl functional groups show a superior e-NRR performance.
